CHENNAI, DEC 30   :    The countdown for the New Year day launch of PSLV/-C58/XPoSat,X-ray Polarimeter Satellite, mission along with 10 other payloads, will begin at the spaceportof Sriharikota on Sunday.

The Indian Space Research Organisation (ISRO) sources on Saturday said the 44.4m tallfour-stage PSLV-C58,vin its 60th flight and fourth under DL variant, with a lift off mass of 260tonnes, will take off from the First Launch Pad at 0910 hrs from the SHAR Range on Monday.

After an eventful, successful and a landmark 2023 with Chandrayaan-3 and Sun exploratory missions, ISRO will ring in 2024 with the launch of the PSLV-C58/XPoSat mission on the New Year.About 20 minutes after the lift off, the 469 kg XPoSat will be injected into an Eastward low inclinationorbit of 650 kms by the four-stage ISRO’s reliable workhorse PSLV Launch Vehicle.

ISRO said PSLV-C58 Mission is to launch XPOSAT Satellite into an Eastward low inclinationorbit.

After injection of XPOSAT, the PS4 stage will be re-started twice to reduce the orbit into 350 kmcircular orbit to maintain in 3-axis stabilized mode for Orbital Platform (OP) experiments.

The PSLV Orbital Experimental Module-3 (POEM-3) experiment will be executed meeting theobjective of 10 identified payloads, supplied by ISRO and IN-SPACe.(UNI)
